They do take out ground loop hum, when it exists, will save your neck from the conductor during a musical performance.
Not having enough of them.
Only rated for 6A per plug (They REALLY need to work on this!)
MAKE SURE that it's a ground loop problem where your setting this up and not an equipment issue, because the conductor doesn't care what it is, and his wand is coming your direction if you don't explain!
These things are super tough in my experience, and I often use them as throw weights for tie line... (Perform this action at your own risk, I'm just trying to say they likely won't break on you)
Yes, I would recommend this to a friend
